Apple isn’t going to touch this with a 10-foot pole.

The provenance “proof” these approaches provide is very tenuous and nowhere near the “this is a real photo of a real world event taken by a real camera and not an AI image” proof that marketing types like to push.

Apple doesn’t want a PR disaster where some crazy image is totally fake but becomes world news because it is “cryptographically signed as being from a real iPhone so it must be real!”

Apple is working on their own system, which is expected to launch with IOS 27: https://www.macrumors.com/2026/08/10/ios-27-apple-reference-...

>Images captured with an opt-in Reference mode can be authenticated to confirm they were taken with an iPhone. Authenticating is done by tapping the Reference badge on the image, which sends the raw image, sensor signatures, capture time frame, and the unique hardware identifiers of the sensor to Apple's Private Cloud Compute (PCC) servers. PCC uses the information to determine whether the camera captured the photo, gives it a unique ID, and then returns an authenticated version to the user's device.
